痛苦的补牙日子就要结束了


From VOA Learning English, this is the Health & Lifestyle report.

VOA英语学习健康与生活频道。 


Many people fear a visit to the dentist.They are not so much afraid of the doctor, but of the dental equipment and treatments.

很多人害怕看牙医。他们害怕的并不是医生,而是对牙科的设备和治疗过程感到害怕。 


Well, fear no more!

现在好了,可以不用害怕了。 



A British company says it has developed technology that will end the need for mechanical cleaning of dental cavities.It also says the technology speeds up a natural process of tooth repair.

一家英国公司称,他们研发的一项技术将摆脱蛀牙清理器械的使用。该公司还称这项技术加速了牙齿修复的过程。


For over a century, dentists have been repairing cavities the same way.They first remove the decayed, or bad, tooth tissue with an electric-powered drill.Then, they fill the hole in the bone with a metallic or plastic substance.

一个多世纪以来,牙医们修复牙齿的方法都没有变化。首先,他们会用电动钻把腐坏的或者不好的牙齿组织移走。接着,他们会用金属物或塑料物在牙齿骨骼上填补这个洞。


If the cavity is not too deep, the experience can be unpleasant.However, if it is deep, near the nerve of the tooth, it can be very painful.The worst part is that the process of drilling and filling the cavity has to be repeated for the entire life of that tooth.

如果蛀牙不是太深,过程中可能只是有点难受。但如果蛀牙很深,并且靠近牙齿神经,那就会很痛。最糟糕的是,那颗补过的牙齿还要在接下来的一生中多次钻孔和补牙。



Rebecca Moazzez is a senior lecturer at King’s College London.She says that this cycle lasts the rest of the tooth’s life.

丽贝卡·毛瑟斯是伦敦大学国王学院的资深讲师。她说这个周期会一直持续直到牙齿脱落。


"You’re really in that cycle of repair and replacement for the rest of the tooth’s life."

“只要还没掉光,那你就要一直补牙或者换牙。”


Tooth enamel is what we see on the outside of the tooth.The enamel of a damaged tooth can be replaced naturally.This process is called re-mineralization.But it is too slow to stop bacteria from building up in small, narrow areas of the enamel.

牙釉质是牙齿外面我们能看到的地方。受损牙齿的牙釉质会自动更新。这个过程叫再矿化。但是再矿化过程太慢,不能阻止细菌在牙釉质狭小的空间里繁殖。


A British business called Reminova has developed a method for speeding-up this natural re-mineralization of early-stage cavities.

一家叫做Reminova的英国公司研发了一种在蛀牙早期加速再矿化的方法。


Jeff Wright is head of the company.

杰夫·赖特是这家公司的老板。



"We’ve just found a way to make that a much faster process.Driving healthy calcium and phosphate minerals into your enamel and, through a natural process, it will bind on and add to the enamel that’s there."

“我们已经发现了一种加速再矿化过程的方法。在牙釉质上注入健康的钙质和磷酸盐矿物,会自然附着在牙齿外生成牙釉质。”


The process begins with a cleaning of the cavity.This does not require power tools.The dentist covers the problem area with a mineral solution, and then uses an electrical current to harden this material.The electricity is too weak for the patient to feel.And the hardened mineral completely fills the cavity.

开始前首先要清理蛀牙。这并不需要电动工具。牙医会用矿化液覆盖蛀牙,然后用电流加固。这种电流很微弱,患者几乎感觉不到。之后这些硬化的矿物质就将蛀牙完全补好了。


Researchers say this method could be especially useful for children. Sometimes children have bad experiences at the dentist.They fear the drilling and injections.Who wouldn’t be afraid?Better experiences as a child might lead to more visits to the dentist as an adult.

研究人员说这种方法特别适合儿童。有时候儿童会有看牙医的不快经历。他们害怕电钻和注射剂。谁不害怕呢?儿时轻松的看牙经历可能会导致他们成年之后多看牙医。


Dr. Barry Quinn works as a consultant at King’s College.

巴里·奎因是国王学院的会诊医生。



"If children have a better experience of going to the dentist, so they haven’t had the necessary drilling and injections for routine fillings,then they’ll be much more positive in later life and probably become much more regular patients."

“如果儿时有过良好的看牙医的经历,那他们就不需要钻牙和补牙,那么他们可能在之后的生活中更加关注牙齿健康成为牙医的常客。”


Dentists say the new method is most effective on early-stage cavities.The whole treatment lasts about as long as a normal drill-and-fill visit.Researchers say they believe the new method can be further developed for treating late-stage cavities.

牙医说这项新技术在蛀牙早期最有效。整个治疗过程和钻牙补牙加起来的时间差不多。研究人员说他们相信这项新技术能够取得突破治疗晚期蛀牙。


And they are quick to note that regular cleaning with fluoride toothpaste helps prevent cavities in the first place.

并且他们很快意识到起初含氟牙膏有助于防止蛀牙。
